Tesla’s Battery strategy is in preparation for two of its most anticipated vehicles

Tesla has continued to attempt to improve its battery packs and cells despite being the industry leader in EV battery tech. Interestingly enough, the electric car company located in Silicon Valley has had some of the best vehicles in terms of EV range in the past ten years. While other car companies were struggling to equip their attempts at electric cars with 100 miles of usable range, Tesla was and has been pushing the envelope since the original Roadster in 2008.

But even though the company has facilitated several vehicles in its fleet to have over 300 miles of range, and one with over 400 miles, it hasn’t been enough to let Tesla’s battery engineers rest. Even though the Model S Long Range Plus configuration packs 402 miles of electric range, which is plenty for most drivers, Tesla has several cars in the works that pack considerably more range than that. These are also not your “run of the mill” EVs, either. They are the Tri-Motor Cybertruck and the next-gen Roadster.

Batteries are what drive an EV to be all that it can be. They are responsible for the range and the performance of the car, along with the motors and engineering of the chassis and body. However, battery tech is ultimately what decides if a vehicle is going to be a successful electric car or just another one to add to the list of underperforming automobiles.

The key to building a great electric car, like anything else, is starting at the foundation. When you want to make a great pizza, you start with great dough. When you want to make a great EV, you start with the battery cells.

The problem with batteries is that there are no two cells that are the same when the materials that are used within are concerned. Not only that, but sometimes the elements that make some batteries stable and help with energy density are controversial. This is the case with cobalt.

But before I go into a spiel about Tesla’s use of cobalt and how the company responsibly sources it, let’s stay on topic.

Tesla’s battery teams in Canada, led by Jeff Dahn at Dalhousie University, released a new paper this week that indicated an electrolyte solution could contribute to increased battery energy density, and could lead to an extended lifespan.

The solution would be used to combat the effects of degradation, and would ultimately lead to a longer life span and increased energy density. Enter the Tri-Motor Cybertruck and Roadster.

Both of these cars have range ratings that are well above the Model S Long Range Plus variant. The Cybertruck’s Tri-Motor will have 500+ miles of range, and the Roadster will have 620 miles.

However, Tesla’s current cells are not capable of holding this amount of range. If the batteries are not capable of holding excessive amounts of energy density, they will not perform in the fashion that they were intended. Therefore, Tesla has to continue developing its cells to promote longer-range driving and a long lifespan.

Starting with the Cybertruck, which has an estimated range of “500+ miles,” according to Tesla’s website. Currently, Tesla does not have a battery pack released that is capable of that kind of range, so the batteries must improve. The Tri-Motor setup will certainly help with the towing capacity and acceleration. Still, the battery pack within the Cybertruck has to work efficiently to not only supply power to those motors, but it also has to maintain energy so it can keep range at a reasonable level.

With the Roadster, things are slightly different. This car will (more than likely) not be towing things or have excessive amounts of cargo in the back, so there isn’t as much involved with maintaining range through laborious work. However, it is one of the fastest cars ever made, and Elon Musk has said in the past that the range of the Roadster will be over 1,000 kilometers or 621 miles.

Ultimately, the development of Tesla’s cells has to continue to improve. Obviously, the battery packs for both of the vehicles that were talked about in this article will have battery packs that are larger than the 100 kWh packs that Tesla puts in the Performance variants of the Model S and Model X. But there is a chance that Tesla equips the Cybertruck and Roadster with smaller, more energy-dense batteries like the 2170 cells that are used in the Model 3 and Model Y.

Lucid’s reveal of the 517-mile range that their new EV, the Air, has, certainly must have lit a fire under the rear-ends of Tesla’s battery engineers. Tesla has had a reputation of being the EV company with the best range, and now that Lucid “technically” has the title for that, even though the car isn’t in production, Tesla will likely be gearing up for a takeback of that label.

Tesla’s battery strategy from here on out will be interesting considering other auto companies have proven they are capable of competing in terms of EV range. There is still the fact that Tesla is actually producing these cars on a massive scale and we know that the company’s cars can perform, we don’t know this about the other vehicles yet.

SpaceX readies Starship Flight 14 for a historic journey into uncharted territory

SpaceX finished Starship’s Flight 14 rehearsal, clearing the way for its first orbital flight Monday.

SpaceX has cleared one of the last hurdles before Starship’s first trip to orbit. The company posted on X Thursday afternoon that its launch rehearsal for Flight 14 was complete, keeping the mission on track for Monday, September 28. The launch window opens at 7:15 a.m. CT at Starbase, Texas, and runs for 75 minutes.

A wet dress rehearsal is essentially launch day without the launch. Crews fill Booster 21 and Ship 41 with thousands of tons of extremely cold propellant, run the countdown nearly to ignition, then drain everything back out. It lets engineers catch leaks or equipment problems before anything leaves the pad. SpaceX still needs a launch license from the FAA before the stack, which stands 407 feet tall, can fly.

Flight 14 matters because of where it is going. All 13 previous Starship flights followed a suborbital path, which works like throwing a ball extremely high and far: the vehicle reaches space, but it is always on a course that brings it back down within about an hour. This time, Ship 41 will perform a short engine firing called an orbital insertion burn roughly 25 minutes after liftoff, giving it enough speed to keep falling around Earth instead of back into it. SpaceX plans about six laps at an altitude near 275 kilometers (171 miles) over nearly 10 hours, as Teslarati detailed when the mission was first announced.


Getting into orbit also means Starship has to prove it can get back out. The ship must relight a single Raptor engine in space to slow down for reentry. SpaceX says it will only attempt the orbital insertion burn after flight controllers confirm the hardware needed for that return burn has enough backup, and its flight plan includes health checks that could shorten the mission to two or five orbits.

Flight 14 is also the first to put working satellites into service. Flight 13 carried 20 Starlink V3 satellites in July, but they came back down with the ship because that mission never reached orbit. This time, 26 V3 satellites are meant to stay up and join the constellation within a few weeks. Together they add about 26 terabits per second of network capacity, which SpaceX says is roughly 10 times what a single Falcon 9 launch of older V2 Mini satellites adds. Three of them carry cameras that will photograph Starship’s heat shield in orbit to check for tile damage before reentry.

The hardware has changed too. Ship 41 flies with extra fasteners on tiles in the most vulnerable areas, fixes for gaps where superheated plasma slipped behind tiles, and curved tiles designed to reduce heating between them. Two tiles recovered from Ship 40 will fly again, the first reuse of any part of a Starship heat shield. Booster 21 carries better engine filtering and new relight software after ice clogged three center engines on the previous booster, leaving only eight of 13 engines to restart for its landing burn.

Ship 41 is targeting a splashdown in the Pacific Ocean west of Chile, a new recovery zone after several Indian Ocean landings, while Booster 21 aims for the Gulf. Neither will be caught by the tower on this flight. Elon Musk said in August that a ship catch was likely “in a few months.”

Google just picked SpaceX for its first step into orbital AI

Google will launch its first Project Suncatcher AI satellite on SpaceX’s Transporter-18 rideshare next week.

Google is about to put its own AI chips into orbit for the first time, and it is paying SpaceX to get them there.

The company said Thursday that the first in-orbit test of Project Suncatcher, its research effort to find out whether space can host large-scale AI computing, will fly next week on SpaceX’s Transporter-18 rideshare mission.

The satellite, called MVP, is about the size of a refrigerator and carries four of Google’s Tensor Processing Units, the same chips Google runs in its ground data centers. Google originally planned to launch two custom satellites in 2027, but chose to move faster by integrating its chips into a satellite.

MVP’s solar panels supply about one kilowatt of power, and Google will run Gemini models on the TPUs only in bursts of roughly 15 minutes before the chips shut down so the radiators can shed heat. In a blog post, Google said its Trillium TPUs survived vibration testing that mimicked sustained launch loads of up to 10g, with individual components seeing 50 to 100g, and handled a radiation dose greater than a five year mission would deliver.

SpaceX and Google mull massive partnership on Musk’s orbital data dream: report

Next week’s flight, slated for October 1, follows a relationship that became public in May, when Teslarati reported that Google was in talks with SpaceX for a launch deal tied to orbital data centers. Google also holds a stake of roughly 6% in SpaceX.

The two companies are chasing the same idea from very different starting points. SpaceX’s own orbital compute program is built around the AI1 satellite, a roughly 70 meter structure derived from Starlink V3 hardware that is designed for 150 kW of peak compute, about 150 times the power MVP will draw. Elon Musk has brushed off concerns about crowding orbit with those satellites, and SpaceX is building its Gigasat factory in Bastrop, Texas, to produce them, targeting an annualized rate of about 1 GW of space compute by the end of 2027.

Musk also posted on X on Thursday that “the amount of compute in space will obviously round up to 100% of all compute.”

Google has been more cautious in public. Its research estimates that launch prices need to fall below about $200 per kilogram before an orbital data center can compete with a ground facility on energy cost, a threshold the company believes could be reached around the mid 2030s. The Suncatcher team has said it expects the effort to remain a project rather than a product for years, which leaves the first real test of its hardware riding on a rocket from the company with the most aggressive timeline in the field.

Tesla Cybercab gets initial tie-in to localized, in-house cathode plant

Published

Tesla has taken another concrete step toward owning its battery supply chain, and it’s doing so with what is perhaps the most important vehicle in its short-but-storied history.

On September 23, Tesla announced that it has officially built the first Cybercab with cathode material produced in-house at the company’s first cathode plant in the U.S., and the first in the U.S. overall.

Active cathode material is the most expensive piece of a lithium-ion battery cell, and it often accounts for more than a third of cell cost. For years, the industry sourced a majority of it from Asia, but Tesla’s decision to make it in the United States bodes well for the Cybercab project. This is the latest chapter in Tesla’s vertical integration strategy, which began in public at Battery Day in 2020.

At the Battery Day Event, Elon Musk said the company would build a North American cathode plant and overhaul the process to cut costs and waste, while also making some of the most powerful and long-lasting cells in the industry.

The Austin facility took years to appear. Tesla filed permits for “Project Cathode” in 2022 on land near Giga Texas. By mid-2022, the building frame was up and Tesla later invested hundreds of millions of dollars as part of a larger expansion of the Giga Texas plant. The company stated it was operating the first large-scale cathode production facility in North America to supplement 4680 cell production.

One month later, that material reached a finished Cybercab.

The timing of this breakthrough is monumental for the Cybercab program. As Tesla officially launched the first Cybercab rides to the public earlier this month, production of the ride-hailing-geared vehicle is moving forward on the planned S-curve that CEO Elon Musk told everyone to expect.

Nevertheless, packs of Cybercab units have been spotted throughout the United States, in an effort to potentially activate the fleet as soon as the company gains regulatory approval in various geographic areas.

On top of that, Tesla owning the cathode step and pairing it with its own in-house lithium from the Gulf Coast refinery shortens the supply chain that once stretched thousands of miles and subjects every pack to fewer external price shocks and geopolitical risks.

Tesla is not yet independent of all of its foreign suppliers, as some precursor metals come from mines and chemical plants. But the first in-house cathode Cybercab shows the company is closing the most expensive and most concentrated gap in its battery production efforts. For a vehicle like Cybercab to operate at a high utilization within the Robotaxi network, that control over cost is so crucial.

It is arguably as important as the software that drives it.
